Miscellaneous inspection tricks with guestfish

This requires libguestfs ≥ 1.7.5, but could be adjusted to work on 1.6

#!/bin/bash -

set -e

guest=$1

# Running a local copy:
guestfish=/home/rjones/d/libguestfs/fish/guestfish
# or:
#guestfish=/usr/bin/guestfish

# Run guestfish as a service.
eval "$($guestfish --listen -d $guest -i)"

# Get the root device.
root="$($guestfish --remote inspect-get-roots)"

# Print some inspection information.
echo "Product name:" "$($guestfish --remote inspect-get-product-name $root)"
echo "OS type:" "$($guestfish --remote inspect-get-type $root)"
echo "Major version:" "$($guestfish --remote inspect-get-major-version $root)"
echo "Minor version:" "$($guestfish --remote inspect-get-minor-version $root)"
echo "OS distro:" "$($guestfish --remote inspect-get-distro $root)"
echo "Architecture:" "$($guestfish --remote inspect-get-arch $root)"
echo "Package manager:" "$($guestfish --remote inspect-get-package-management $root)"
echo "Package format:" "$($guestfish --remote inspect-get-package-format $root)"

# Shut down guestfish service.
$guestfish --remote exit
